Getting Interface error

arghyadeepg0092

Getting below error in a simple Add vehicle form that I created during training. File upload control is not working at all

 This is how the File upload control has been configured

a!fileUploadField(
label: "Image",
labelPosition: "ABOVE",
target: cons!AX_DOCUMENTS_FOLDER_POINTER,
maxSelections: 1,
value: ri!vehicle['recordType!{2f4a1797-5b65-4891-a7cf-42ddbb49c8a6}AX Vehicle.fields.{ac064698-12ee-46cc-aebd-629ecc0dedae}vehiclemileage'],
saveInto: ri!vehicle['recordType!{2f4a1797-5b65-4891-a7cf-42ddbb49c8a6}AX Vehicle.fields.{d5103e88-da32-42aa-9559-ec1004b4ce57}vehicleimage'],
